What is the MUTCD?

The Manual on Uniform Traffic Control Devices (MUTCD) has been prepared by the US Department of Transportation, Federal Highway Administration, to set forth the basic principles which govern the design and use of traffic control devices. The Manual was developed with input from technical experts from many organizations including state, county, and municipal governments. This manual is the national standard used to provide clear and consistent uniform guidance to the traveling public including simplifying driver decisions by promoting instant recognition and understanding. The MUTCD is available at http://mutcd.fhwa.dot.gov/
